The locations include the CastelloRistorante in Banff, as well as the Asian Buffet, Long's Chinese Food and the South Silk Road Restaurant in Calgary.

AHS says anyone who visited those locations at those times may be at risk for developing measles.

Those individuals are advised to monitor themselves for symptoms of the highly-contagious disease, which could include fever, cough and a blotchy red rash that appears several days after the fever, beginning on the face and behind the ears and moving down the body.

AHS is asking anyone showing those symptoms to stay home and call Health Link Alberta at 1-866-408-5465 before visiting any health-care facility or provider.

Officials also said the most recent case is not travel or school related, and the person who contracted measles was likely not immunized. The person worked at the Asian Buffet on Bonaventure Drive southeast on several dates from April 8-17, say health officials.

In Edmonton, a fifth measles case has been confirmed in an infant under 12 months old.

AHS officials say the outbreak of measles in the province underscores the importance of immunization.

Dr. Glen Armstrong of the University of Calgary says measles is highly infectious for those who haven't been immunized. He says the measles virus can hang around in the air for hours after an infected person has left.
